Folder thumbnails

[mcam]

Is there a setting in XnView MP to revert folder thumbnails to the portrait format they had in XnView Classic? The folder thumbnails in Classic (left in the image) made better use of the allotted thumbnail space then the ones in MP (right of the image).

currently no

My fault. I resized the thumbnails but forgot to rebuild. Once rebuilt, the folder thumbnails correctly fill their cell.
